If you're at all interested in a new industry, there is usually a podcast focused on that vertical where notable luminaries get interviewed. Listening to a few hours of shows, while doing chores or commuting, can get you up the learning curve fairly quickly.

And the tendency to prattle can be fairly helpful. It helps illuminate the thought process of the subject in ways you wouldn't get in more formal settings, or in the few sentences of quotations that appear in a press account.

Thats exactly the aspect of why I listen to podcasts. If you need to clean your apartment, go for a longer walk or anything else were you cant read or look at a video instead.

...or when doing yard work or other chores around the house. I'll also listen when getting ready in the morning or when cooking dinner.

I listen while working out or while at work if I'm working on something that is not that intense.

when i'm in the car, walking, or riding my bicycle.
